Overview
LC898201 is the appropriate motor control LSI for the surveillance camera
usage, and it can drive iris, focus, zoom and Day/Night switching
simultaneously.
It incorporates two feedback circuits for iris and focus control, and two
stepper motor control circuits for zoom and Day/Night switching (cf. P4
Application-1).
Moreover, the feedback control applies iris control, and stepper motor
controls apply focus, zoom and Day/Night switching at the mode selection
(cf. Application-2 to 4 of P5 to P7).
Stepper motor control circuits can drive the stepping motor efficiently(It is
called “ECO(GREEN)-driver”) (For a limited numerical usable channel,
refer to Application-1 to 4 of P4 to P7).
